HU to amp connections

[ALUCARD19]

When going from the speaker outs on my HU KDC-X798 to my amp SS PN4.520D should I use the hi-input wires or is it better to use the RCA outs from the HU to the amp inputs

Use the RCA's

RCA's

I was looking at the NVX XIX205 .5m twisted wire RCA interconnects is this brand any good.
100% Silver Tinned Oxygen-Free-Copper
Flexible PVC Insulation - Dual twisted construction for signal transfer that guards against noise interference (RFI)
Black nylon braid to prevent chaffing and electromagnetic interference
